Unit 9: Our Solar System
In this unit, pupils learn about the Solar System — the Sun, the Moon, the planets (especially Venus), rockets, satellites, space stations, and space telescopes. They read about Venus, write a description of Mars, study prepositions of position (above, below, between), and recite a poem, 'Little Red Riding Hood and the Wolf' by Roald Dahl.
Nurul and her friends are in the Planetarium gardens. The Earth is a planet in the Solar System. Pupils read a passage aloud:
Other planets: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune
All these planets travel around the Sun.
We see the Sun in the daytime, but at night we see the Moon.
The Moon is a natural satellite that travels around the Earth.
Pupils give directions to get from one Planetarium garden to another (e.g. Venus Garden to Saturn Garden).
Pupils state True or False on these space tools:
A rocket takes photos of things in space. (False — it launches objects.)
A satellite is used to forecast weather. (True)
A space station is launched as one complete piece. (False — assembled in space.)
A space telescope is used to launch a rocket. (False — used to observe space.)
Astronauts live on space stations. (True)
Venus is the second planet from the Sun, located between Mercury and Earth:
Venus and Earth are almost the same size. It is the closest planet to Earth.
Venus does not have seas or living things.
Thick clouds over Venus keep the heat in. The temperature during the day is so hot that even metal can melt.
The surface of Venus is covered in dried lava from old (not active) volcanoes.
Venus is special because it spins slowly and in an opposite direction from the other planets.
The clouds on Venus reflect sunlight — that is why Venus looks so bright from Earth.
Kim Seng prepares a PowerPoint presentation on planet Mars:
Mars is named after the Roman god of war.
It is the fourth planet from the Sun, next to Earth.
Mars is about half the size of Earth.
The surface of Mars is rocky and cold.
The soil on the planet is reddish-orange.
It takes 687 Earth days to travel around the Sun.
An orbit is a curved path followed by an object in space as it moves around another object.
Pupils rewrite a paragraph about Neptune using word form for numbers:
2 thick and 2 thin rings → two thick and two thin rings
4 of the moons orbit the planet within the rings → four of the moons
1 of Neptune's moons is called Triton → one of Neptune's moons
Prepositions show the location of an object or person:
| above | higher than — 'The thick clouds above the surface of Venus keep the heat in.' / 'The moon is shining brightly above us.' | |
| below | lower than — 'When I am up in a hot air balloon, everything looks tiny below.' / 'The moonlight is reflected in the lake below it.' | |
| between | in the space separating two objects — 'Venus is located between Mercury and Earth.' / 'Saturn is located between Jupiter and Uranus.' | |
A poem by Roald Dahl. Pupils recite and answer questions about their favourite character:
'Red Riding Hood stopped. She stared, and then she said, 'What great big ears you have, Grandma.''
'All the better to hear you with,' the Wolf replied.
Wolf thought, 'I'm going to eat this child. So no matter what she says, I'm going to eat her anyway.'
Pupils discuss: Which is your favourite character? Why?
Our Solar System has 8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. All travel around the Sun. The Moon is a natural satellite of the Earth.
Venus is special — it spins slowly and in an opposite direction to the other planets, and its thick clouds reflect sunlight making it look bright from Earth. Its surface is covered in dried lava from old volcanoes, and the day temperature is hot enough to melt metal!
Prepositions of position: 'above' (higher than), 'below' (lower than), 'between' (in the space separating two things). Example: Venus is located between Mercury and Earth.
📝 Kosa Kata
Venus is often called Earth's 'twin' because they are almost the same size — but Venus is the hottest planet in our Solar System! Its thick clouds trap the heat so well that the temperature during the day is hot enough to melt metal. Venus also spins in the OPPOSITE direction to all the other planets!
